kristopher,

LNT is accepted as a conservative overprediction that can be used for drafting things like regulations.

I don't know of ANY legitimate scientist in the medical radiation field that accepts LNT as an accurate model of what biological tissues ACTUALLY do.

The LNT model is an approximation and an approximation that will always OVER PREDICT the effect.

Therefore, it is useful in writing things like regulations; because it is conservative because it always over predicts.

Therefore, if you make a regulation that says someone can get no more than 10 mSv when calculated by the LNT model; then you know that the ACTUAL dose / radiation damage will be LESS than 10 mSV.

After all THINK about it. The original post of the thread is how scientists used the new supercomputers at Los Alamos to calculate all the physics that goes into determining the amount of biological damage. Then someone says that an EXACT SOLUTION is given by:

y = a*x

Give me a break!! The LNT model is a MODEL; nothing more.

The biological damage done by radiation involves extremely complex chemistry and physics; hence the use of the supercomputer.

It is NOT going to EXACTLY equal the result that comes from:

y = a*x

LNT is a MODEL and NOT reality.
